Other differences are : The limiting proportions - the dividing line between thin and thick - is …

WebThe maximum stress criterion, also known as the normal stress, Coulomb, or Rankine criterion, is often used to predict the failure of brittle materials. The maximum stress criterion states that failure occurs when the maximum (normal) principal stress reaches either the uniaxial tension strength σ t, or the uniaxial compression strength σ c, -σ WebThe shear modulus is the proportionality constant in Equation 12.33 and is defined by the ratio of stress to strain. Shear modulus is commonly denoted by S: 12.43.
